2.2.21 Track Recoil Springs

If you are making repairs to a machine
equipped with tracks, always be aware of the
dangers involved with track recoil springs. This
spring is under extreme pressure at all times.
If it is disassembled by mistake, the spring
may

y out and cause serious injury.

Be careful when removing or installing tracks
on track-type machines. When removing the
master track link the track system may sepa-
rate suddenly and cause possible injury.

Always stand clear of the track travel path
when separating the master link section of the
track.

2.2.22 High-Pressure Fluid Lines

Always keep in mind that these systems are
under high pressure. When inspecting or re-
placing piping or hoses, always check to be
sure the pressure in the system has been
relieved before proceeding. Working on a sys-
tem still under pressure could lead to serious
injury, always do as follows:

●

If you will be removing a line or component
with fluid in the system, always cap and
seal the opening to avoid leakage or sys-
tem contamination.

●

Never carry out inspections or replace
items while the system is under pressure.

●

Never use any part of your body to check
or feel for leaks. Always wear safety
glasses and leather gloves when checking
for leaks and use a piece of wood or card-
board when checking for leaks from small
holes.

2.2.23 Safe Work Preparations

Before starting any repairs, be sure the ma-
chine is sitting on a level stable surface.

Lower all the work equipment to a safe and
stable position on the ground. Turn the engine
OFF and neutralize the work equipment con-
trols by rotating them to the left and right (joy-
stick control) or moving them back and forth
(lever control). This function will relieve system
pressure.

Block the tracks (if equipped) or wheels (if
equipped) with chocks to prevent the machine
from moving.

If equipped, set the hydraulic lock lever in the
LOCKED position. If equipped, set the parking
brake in the PARK position.

Be sure all personnel and equipment is clear
of your work area and you can be seen by all
working personnel especially if performing re-
pairs in the

eld.
